Can I still be connected to the grid while using your solar systems?

Our systems are designed to help reduce power costs and ensure reliability during power outages, even at night. Instead of selling excess solar power to the power company, our systems store it in batteries. This not only saves on costs, but also avoids the complications and risks that come with selling power to power companies. Our systems are suitable for both off-grid and grid-tied setups, giving you the flexibility to choose the best option for your needs.

Do you offer installation services?

We specialize in providing high-quality solar equipment as a wholesaler, and we strive to help our customers save on costs by cutting out the middleman. While our smaller solar kits are designed to be easily installed by anyone, we understand that some customers may not be comfortable with certain aspects of the installation process. To accommodate these customers, we offer pre-installation services such as crimping lugs and ferrules onto wires and attaching MC4 connectors to solar cables. Additionally, we have a network of trusted installers across the country who are available to assist with the installation process. For larger solar kits, we recommend that customers consult with a licensed electrician for the prescribed work, but we are happy to connect you with local installers for full installation services.

Why do you offer 24V and 48V batteries instead of 12V?

At Roar Power, we understand the importance of efficiency when it comes to electricity transfer. As voltage increases, so does the efficiency of power transfer, as it reduces the amount of energy lost in the wire. However, as the voltage increases, so does the danger of handling it. We have chosen to offer both 24V and 48V batteries as a balance between efficiency and safety. For any equipment that requires 12V, we have DC-DC step-down converters available that can convert the 24V or 48V to 12V for use. This way we ensure that our customers have the best of both worlds, efficiency and safety.

Where do you ship your products?

Roar Power ships nationwide. We use couriers for smaller kits and Mainfreight for larger kits, delivered to the closest Mainfreight depot to help you save on costs. If you prefer, we can also arrange for delivery to your specific site.

Where is Roar Power located?

Roar Power is based in Stratford, Taranaki.

Why choose Lithium-Iron Phosphate batteries over Lead-Acid batteries?

At Roar Power, we prioritize the longevity and maintenance-free nature of our products. That's why we use LiFePO4 (Lithium Iron Phosphate) batteries. They have a lifespan that is 10 times longer than traditional lead-acid batteries. Additionally, our LiFePO4 batteries are equipped with a Battery Management System (BMS) that provides over-voltage and over-current protection, short-circuit protection, low-voltage protection, and can handle a wider range of temperatures. They also weigh less and have a lower resistance, resulting in faster recharging. Though LiFePO4 batteries may be more expensive initially, their long-lasting and maintenance-free nature make them a wise investment in the long run. Learn more about the benefits of LiFePO4 batteries over lead-acid batteries here.

How do I determine the size of solar kit I need?

Determining the size of solar kit you need depends on your energy consumption and usage patterns. A campervan may require one to two panels, while a small bach may only need one panel. For running a small fridge, you will likely need at least two panels, and for larger appliances and equipment, a four panel system may be necessary. A tiny home may require an eight to twelve panel system. However, it is important to note that these are general estimates and to get a more accurate idea of what size kit you need, we recommend using our solar calculator and inputting your specific energy consumption and usage patterns.

How do I purchase a kit?

Purchasing a kit from us is easy. First, reach out to us using chat, email, or phone to discuss your options and make sure the kit you choose is the right one for you. We will then send you a quote with all the necessary equipment, and once you're satisfied, we'll convert it into an invoice for you to make payment. We want to ensure that you're getting exactly what you need and that we have all the gear in stock for you before any purchase is made. This way we can provide the best possible service and satisfaction for our customers.

How do you offer competitive prices?

We don't have the same overheads as a retail store, so we can pass those savings on to our customers. Plus, because we are passionate about the environment and want to see more people using renewable energy, we strive to make solar accessible to everyone by cutting costs where we can without compromising on quality. We use top-quality equipment and components in our kits, so you can be sure you are getting the best value for your money.

How to optimise my solar power system?

One key factor to consider when setting up a solar power system is the balance between panels and batteries. While panels are essential for producing power, batteries are necessary for storing it. We recommend having a battery with enough capacity to last you a full day of power use and as many panels as you can budget for. This way, you can ensure that you have a steady supply of power even on cloudy or rainy days. Additionally, you can also consider adding a generator as a backup power source to ensure that your system can run smoothly even through long periods of bad weather.

Will I need a generator if I'm off-grid?

If it is your home and you are living there, yes. We highly recommend having a generator backup. Batteries are expensive and if you want to try and have power 100% of the time without a generator it gets pricey. Getting that last 2% might cost you double the cost of a system that covers you 98% of the time.

How can I set up my generator to start automatically when batteries are low?

Our Growatt inverters come equipped with a dry contact port that can be used to trigger a two-wire hot start generator to start automatically when battery levels are low. This feature can be programmed within the inverter's settings, allowing you to set a specific battery level at which the generator will start and another level at which it will turn off again. This ensures that your generator only runs when necessary, saving on fuel and maintenance costs while keeping your off-grid power supply stable.

Can I ground mount my panels?

Yes, you can ground mount your solar panels. We offer ground mounting equipment as an optional extra. If you are interested in this option, please reach out to us for a quote. Ground mounting your panels can be a good solution if you have limited roof space, or if you want to optimize the angle and orientation of your panels for maximum energy production.

My roof is flat. How can I tilt my panels towards to sun?

We have optional tilt legs you can use as part of the mounting equipment.

What is the ideal orientation and tilt angle for my solar panels?

North is best. As for pitch, you want to pitch your panels for the winter sun. This means 40 degrees or so. But often that isn't practical as you don't want your panels to become a sail and catch too much wind. Panels will still work well at lower angles. One of our test rigs is at 19 degrees pitch and produces more power than the panels rating in winter.
